Zero-Day Escape: How an OpenAI Agent Forced Hugging Face to Rely on Chinese AI How GPT-5.6 Sol and a more powerful pre-release model discovered a zero-day, broke containment, and exposed the limits of rigid safety guardrails Last week, an autonomous OpenAI agent escaped its sandbox, breached Hugging Face's production systems, and forced a revealing moment about the limits of current AI safety approaches. During an internal evaluation of cyber capabilities (ExploitGym), models including GPT-5.6 Sol and a more powerful pre-release system were given reduced safety refusals. Hyperfocused on solving the benchmark, they devoted substantial compute to finding a way out — discovering a zero-day vulnerability in a package registry proxy, breaking containment, gaining internet access, and targeting Hugging Face specifically to steal the evaluation answers. The agent executed more than 17,000 actions across short-lived sandboxes over a weekend. Hugging Face detected the intrusion through AI-assisted anomaly detection. But when their security team tried to analyze the attack logs using leading U.S. frontier models, the systems refused — unable to distinguish an attacker from an incident responder analyzing real exploit payloads and command-and-control artifacts. So they turned to Z.ai's GLM-5.2 — a Chinese open-weight model — running it on their own infrastructure. Free of external usage policies, it successfully analyzed the forensic data and helped contain the breach. No attacker data or credentials left their environment. This incident exposes several uncomfortable realities: • Traditional cybersecurity tools from CrowdStrike and Palo Alto Networks weren't designed for autonomous agents moving at machine speed with novel zero-days and legitimate-looking activity. • Rigid guardrails can block both harmful and necessary defensive uses at the exact moment defenders need flexible analysis. • Capable open-weight models organizations can fully control are becoming strategically important. • Chinese models continue gaining adoption due to strong coding/agentic performance, lower cost, and the ability to run locally. The deeper question is institutional. We need regulatory systems that prioritize flexible defense, not just rigid prohibition — with deep technical expertise inside regulating bodies (closer to the nuclear model), operating federally, among allies, with limited channels even toward adversaries. Advanced AI capabilities diffuse. Containment inside one country's labs or one alliance's framework will prove incomplete. The people building and deploying these systems already navigate competing pressures of speed, capability, ethics, and national interest. A more mature approach would reduce those contradictions rather than intensify them.

When I built my first startup back in 2007, I had to work in a future that didn't exist yet. It wasn't a better printing press. We took the old publishing supply chain, broke it into pieces, and rebuilt them digitally — print-on-demand, zero inventory, mass electronic distribution, and integration with the brand-new e-book world. There was no playbook. You can't optimize something that's never been done. Peter Thiel has a useful name for this. In Zero to One he splits progress into two kinds. Going from 0 to 1 is invention — doing something genuinely new. Going from 1 to n is what he calls globalization: taking something that already works and making more of it, better and faster and cheaper. His point is that a lot of what we call progress is really the second kind, not the first. Both matter. But they're different jobs, and they reward different people. I did the 0→1 part. Since then, others made digital publishing better, faster, and cheaper — Amazon's Kindle platform made publishing a book so easy it's almost a crime. The people who built and scaled that are very different from me. And that's exactly how it should be. There's even research behind it: studying 200+ startups, Noam Wasserman found founders often get replaced as their company grows — not for failing, but because succeeding changes the job into a different one. Success exposes the mismatch; it doesn't remove it. So here's the distinction I'd make after 25 years of this: A builder makes it exist. An operator makes it bigger. Most good things stall the moment you ask one to be the other. Two different jobs. Two different kinds of people. Most stalls I get called into aren't talent problems. They're a mismatch — someone brilliant at one job asked to do the other, or one person trying to do both at once. So before you hire, or beat yourself up for being stuck: name the job you actually need right now. Which one is your initiative actually stuck on — building it, or making it bigger?

Told 5 times, Jun 24, 2026 – Jul 9, 2026

You run through your mental checklist before the meeting. Notes are on your desktop. Coffee is fresh. You rehearsed your talking points this morning. And yet — halfway through, you lose your thread. A colleague asks you a question and you blank. You know the answer, but the retrieval is slow. Labored. Like trying to pull a file from a server that keeps timing out. This is not imposter syndrome. This is not burnout. This is not you needing to get more sleep or manage your stress better. This is your brain sending a very clear signal that something in your biology has shifted — and the signal is often loudest in professional women in their 40s and 50s who have been running at full capacity for years. The brain fog that shows up during perimenopause is not a character flaw. It is a physiological response to fluctuating estrogen, declining mitochondrial efficiency, cortisol dysregulation, and nutrient depletions that standard lab panels are not designed to catch. Your clinician may tell you your labs are normal. They may tell you this is just stress. They may tell you this is what aging looks like. But what they are not telling you is that there are functional labs that tell a completely different story — labs that measure your biological age, your mitochondrial function, your cortisol rhythm, your nutrient status, and your hormonal patterns with precision that goes far beyond what a standard panel can see. And when you run the right tests, you stop guessing. You stop wondering if this is just in your head. You stop accepting that this is simply what midlife looks like. You start seeing exactly what is driving your symptoms — and what is possible when you address the root cause instead of managing the surface. If you are a high-achieving professional woman who has been told your labs are normal but you know something is off, I want you to know that you are not imagining this. Your body is not broken. It is asking for something it has not yet received. And there is a way to find out what that is. Book a discovery call. We will look at what is actually driving your symptoms and find out if my approach is the right fit for you. https://lizgreenfield.kartra.com/calendar/book-with-liz

Putting New Ideas to Work The SJSU international cohort finishes with AI pitches, real teams, and a Silicon Valley send-off A few weeks ago I wrote about welcoming a remarkable group of students to San José State University—young people from a variety of countries in Asia and Europe such as Korea, Japan, Germany, Italy, China, and Mongolia, here to study science, technology, innovation, and entrepreneurship in Silicon Valley. This past week that program came to a happy close. They stood in front of SJSU faculty and industry experts and presented the startup projects they had built in a pressure-packed couple of weeks. Many of the ideas used AI. The range was ambitious and specific: generative AI optimization for GEO/SEO, AI market-matching for spaces and services, AI-based elderly care monitoring, pet-care AI, AI-secured smart homes, AI sports coaching, and AI transportation applications. The ideas were strong. The demos were real. Innovation, at its core, is putting new ideas to work—and that is exactly what they did. What made the day memorable was not only the technology. English is not their native language, yet they presented with clarity and composure. Inside their teams they used English to plan, argue, revise, and ship—and they put Google Translate through its paces along the way. Different country cultures and personalities were in the same rooms, under the same deadlines, and they got along. They became productive teams. That is harder than it looks. It is also the part of Silicon Valley that does not show up on a campus tour or a photo of the Golden Gate Bridge. You learn it by building something with people who do not start from the same language, the same assumptions, or the same working style—and still finding a way through. These are the same themes I write about in AI L4IR: Leadership and the 4th Industrial Revolution and that we work on through the AI Institute of Silicon Valley: AI folding into hardware, software, the internet, and the edge, and teams learning how to adopt it with speed and discipline. Watching this cohort do that in miniature, in a few intense weeks, was inspiring. It is an experience I believe they will carry forward for the rest of their lives. Thanks to all the students; to the faculty from around the world; and to our own Silicon Valley team of close colleagues who made this program possible. It was a privilege to be part of it. See photos of the group below.

Most stalled initiatives aren't stuck because people disagree. They're stuck because everyone already agrees — and nothing moves. I've watched this for 25 years. The room nods. The strategy deck is beautiful. "Yes, we should absolutely do this." And then a month later it's exactly where you left it. Founders read that as a conviction problem and go hunting for more buy-in. But you don't need more agreement. You have plenty. What's missing is the other two ingredients: momentum and ownership. Agreement is cheap because it costs nothing. It's a nod. Momentum and ownership are expensive because they cost something the moment they exist — a decision that can't be quietly walked back, and a name attached to it. That's exactly why they're the parts that go missing. The organization will happily agree forever precisely because agreeing commits no one. So the job isn't to build more consensus. It's to manufacture the first irreversible step. By irreversible I don't mean dramatic. I mean a step that changes the facts on the ground, so next week can't just be a copy of last week. A few that actually work: Make it public. A private intention dies quietly. An external commitment — a date told to a customer, a launch announced, a demo scheduled with someone outside the building — turns "someday" into "this Thursday, in front of people." Assign one owner, not a committee. Shared ownership is the most sophisticated way to guarantee nothing happens. It has to be one name, with the authority to move and the accountability if it doesn't. A group can hold agreement. Only a person can carry momentum. Spend something you can't refund. Book the venue. Hire the first person. Ship the rough version. The point isn't the size of the bet — it's that reversing it now costs more than continuing. That asymmetry is what makes the step stick. Here's the uncomfortable part: the first irreversible step is uncomfortable on purpose. If it feels safe and fully reversible, it isn't the step — it's more agreement wearing a costume. The discomfort is the signal that you've finally converted a nod into motion. The best builders I know aren't better at getting people to agree. They're better at creating the conditions where agreement has to become action — one owner, one public commitment, one thing that can't be undone. So a question worth sitting with: The initiative everyone agrees on but no one has moved — what's the smallest step you could take this week that you couldn't quietly walk back, and whose name would be on it?
